The four destitute friends go to a wise man who gives each one of them a magic shell to be placed on top of the turban, from a Tuti-nama (Tales of a Parrot): Forty-seventh Night

The seated wise man drops a small, red shell into the final friend’s outstretched hands. He then instructs each of them to go out into the world and walk until the shell falls to the ground. If the man digs where the shell lands, he will find something to sustain him.
